Definitions

  • the invention relates to a method for dialog-controlled Operation of electronic devices.
  • An operating mode is closed under dialog operation of a device understand at which to process an order or a Task to set subtasks and their solutions alternate.
  • the subtasks are set by the Users, for example, by entering text using the keyboard, by selecting certain symbols on a screen or through spoken commands using speech recognition techniques can be converted into control commands.
  • After The user receives a solution to the corresponding subtask a feedback and if necessary also hints or questions about next subtask.
  • the user friendliness of a dialog system is next to the response times of the system depend essentially on the type of Commands formulated by the user.
  • the invention is based, which To increase the usability of a dialog system.
  • a first variant for the feedback and questions to a certain subtask is used and that after a predetermined number of dialogues carried out for the further dialogues the user the use of a second Variant for the feedback and questions is offered.
  • the invention can be used particularly advantageously if the dialogue, at least in part, using spoken language to be led.
  • the invention is based on an exemplary use in a voice dialer shown in the figure closer explained.
  • this voice dialer In a conventional telephone terminal, when the handset is lifted (colloquially: handset), the alarm clock (bell) is switched off by the fork or hook switch and the circuit for the loop current coming from the exchange is closed.
  • the number dialed by means of a button or dial is sent to the switching center in the form of pulses, that is, interruptions in the loop current of approximately 50 msec with pauses of approximately 50 msec.
  • a 2 out of 4 code is used for devices with a multi-frequency dialing keypad. Two groups of 4 frequencies between 697 and 1633 Hz are provided. When a certain key is pressed, 2 frequencies, one from each group, are transmitted at the same time. With this code, 16 different combinations can be formed, 10 of which are assigned to the 10 digits.
  • the aforementioned voice dialing device is now connected via the analog / digital interface ADS into the connection between the terminal and the switching center, the so-called trunk line AL.
  • the device is activated by the Loop current activated.
  • a signal arriving from the terminal is digitized and in the Signal processor DSP in a first step analyzes whether it language or a dial signal or dial tone acts. If there is a dial signal or dial tone, then the voice dialer back in via the control processor put the inactive state.
  • the Detection process initiated in the signal processor DSP. This runs according to the method described in EP 0 595 889 for recognizing single words of spoken language in which Correlation relationships between the spectral components of the Speech signals are determined as typical characteristics and classified using a neural network.
  • the telephone number assigned to this word is transmitted via the multi-frequency transmitter DTMF as a dial tone sequence or via the pulse transmitter IPS as Dialing signal sequence sent to the exchange and thus the dialing process is carried out.
  • the recognized word is about the Analog / digital interface A-DS acoustically output to the handset of the telephone terminal and / or via acoustic part AT and loudspeaker LS, and so the caller receives feedback about the successfully completed one Given recognition process, or in the case of a negative result, if no match could be found with a stored reference pattern, an indication that the input must be repeated.
  • the training of the words to be recognized takes place in the so-called Learning mode of the device. For this, the respective telephone number entered using the telephone keypad and the associated name spoken into the handset. This is done by spoken instructions of the device supported.
  • the sequence of the control dialog during the learning process for a new entry is shown below, the voice inputs of the user and the voice messages of the device being shown in italics: After picking up the handset, you will hear a prompt. When the number 101010 is selected using the keyboard, the main operating menu of the device is then called up.
  • the device If there are fewer than 9 entries in the phone book, the device generates a spoken message about the number of free places, eg " 6 places free”.
  • the device provides the feedback "Training” and "Dial the phone number.”
  • the number to be entered in the phone book must be entered using the keyboard.
  • the device repeats the number and prompts with the message "Confirm with zero.” to confirm.
  • the number is entered in the phone book and the user is asked to enter the associated name by voice. "Say the related name.”
  • the device After entering the name such as "Sabine” , the device prompts you to repeat it at least once. "Say the related name.
  • the learning process is then completed with the user with the voice prompt "Done" and the device returns to the main operating menu, from which, for example, another telephone book entry can be made.
  • the neural network is trained according to EP 0 595 889 with the new telephone book entries and the device is ready for dialing using spoken language.
  • An existing phone book entry can be replaced by another Training processes in terms of recognition quality can be improved, but it can also be used for several Speakers are set up.
  • the Du word is now offered to the user after repeated entry into the menu and a predetermined number of dialing processes. If the user accepts this offer, the device will use the confidential " you " instead of the distant "you” as a form of address . For example, instead of “If you choose one, you can exercise. If you choose two, then " the phrase "If you choose one, you can exercise. If you choose two, then .” .. "is used and the familiarity acquired by the user in handling the device is also documented linguistically.
